REDWOOD CITY (CBS / AP) — A man accused of kidnapping his two children from their South San Francisco home and taking them on a stolen yacht for three days said Tuesday that he knew he had “gone crazy” but never endangered them.

During a jailhouse interview, Christopher Maffei told the San Francisco Chronicle that he stole a 41-foot sailing yacht from an Alameda marina on Sept. 4, but as he passed the Golden Gate Bridge, he began to have some doubts about taking his kids without a set destination.
